Abstract
The utility model discloses a kind of mine worked-out section high intensity windbreak with pressure relief, including wall, the front of described wall is trapezoidal faces, and trapezoidal faces are in the cambered surface of evagination, the front of described wall is horizontally disposed with from top to bottom some wind guide strips, and the distance between adjacent two wind guide strips are equal, and described wall front center is provided with air-flow release through hole, the side of described wall is trapezoidal faces, and some reinforcement anchor poles are vertically arranged with described wall.Wind guide strip of the present utility model can split the air-flow of explosion shock, and air-flow is oriented to wall both sides, effectively mitigates wall pressure, and air-flow release through hole can further mitigate the pressure that explosive blasting shock wave is caused to wall；Contour structures of the present utility model and the internal reinforcement anchor pole for setting can effectively improve intensity, have the advantages that safe.
Description
Technical field
The utility model belongs to mine operation affiliated facility technical field, and in particular to a kind of mine with pressure relief
Goaf high intensity windbreak.
Background technology
The exploitation position of some mining area segmentations is special, for example, there is old working road and near transport section, the life to adjacent area
Product and ventilation condition can be impacted, therefore, just it is impermissible for being collapsed using traditional goaf free breakage and pressure during such case
The handling process such as fall.And because the impact air-flow of explosion of opening a mine is more, one side air-flow can scurry into Lian Daonei influence environment and lead to
There is potential safety hazard in wind, still further aspect.
Therefore, research and development one kind there can be pressure relief, stop impact air-flow, safe, intensity is high, long lifespan gear
Brattice is the key for solving the above problems.
Utility model content
The purpose of this utility model is to provide a kind of mine worked-out section high intensity windbreak with pressure relief.
The purpose of this utility model is achieved in that including wall, and the front of described wall is trapezoidal faces, and trapezoidal
Face is in the cambered surface of evagination, and the front of described wall is horizontally disposed with from top to bottom some wind guide strips, and two adjacent wind-guidings
The distance between bar is equal, and described wall front center is provided with air-flow release through hole, and the side of described wall is trapezoidal
Face, is vertically arranged with some reinforcement anchor poles in described wall.
The beneficial effects of the utility model：Wind guide strip of the present utility model can split the air-flow of explosion shock, and air-flow is led
To wall both sides, effectively mitigate wall pressure, and air-flow release through hole can further mitigate explosive blasting shock wave to wall
The pressure for causing；Contour structures of the present utility model and the internal reinforcement anchor pole for setting can effectively improve intensity, with peace
Full property advantage high..

Specific embodiment
The utility model is further described below in conjunction with the accompanying drawings, but the utility model is subject to never in any form
Limitation, based on any conversion or replacement that the utility model training centre is made, belongs to protection domain of the present utility model.
The utility model as shown in 1 ~ Fig. 4 of accompanying drawing includes wall 1, and the front of described wall 1 is trapezoidal faces, and trapezoidal faces
In the cambered surface of evagination, the front of described wall 1 is horizontally disposed with from top to bottom some wind guide strips 2, and two adjacent wind-guidings
The distance between bar 2 is equal, and the described front center of wall 1 is provided with air-flow release through hole 3, and the side of described wall 1 is
Trapezoidal faces, are vertically arranged with some reinforcement anchor poles 4 in described wall 1.
The length of described wind guide strip 2 extends to the two ends of wall 1.
Described wind guide strip 2 is the distance between two neighboring equal with the width of wind guide strip 2.
A diameter of 20 ~ 40cm of described air-flow release through hole 3.
Described reinforcement anchor pole 4 is reinforced anchor bolt.
Described wall 1 is concrete wall.
The material of described wind guide strip 2 is concrete.
Utility model works principle and the course of work：When explosion, air-impingement airflow strikes are of the present utility model
Front, is split by wind guide strip 2, and then air-flow is oriented to the both sides of wall 1 along the front of the arc of wall 1, is oriented to the both sides of wall 1,
And the air-flow part at the positive middle part of wall 1 sprays from release through hole, further mitigate the pressure that the front of wall 1 is subject to；
Contour structures of the present utility model and the internal reinforcement anchor pole for setting can effectively improve intensity.
Advantage of the present utility model：Wind guide strip of the present utility model can split the air-flow of explosion shock, and air-flow is oriented to wall
Body both sides, effectively mitigate wall pressure, and air-flow release through hole can further mitigate explosive blasting shock wave and wall is caused
Pressure；Contour structures of the present utility model and the internal reinforcement anchor pole for setting can effectively improve intensity, with security
Advantage high.
